Do you like them? Are you just unable to be bothered enough to write one? Think they're overrated? Underrated?
Personally, my char description is just a few lines describing Kenji, his height, his accessory, and his voice. Things that I think are important to introduce to someone upon a first glance/interaction. I'm also too lazy to type funny to imitate an accent, so I just describe him as having a New England accent xd.
